Indicates mis-predicted branches that occur because the processor predicted an incorrect path. To rebuild all performance counters including extensible and third-party counters, type the following commands at an Administrative command prompt.

INI contains the proper information. You can copy this file from an identical machine to restore the counters. There may be slight differences in this file from machine to machine. But if you notice a drastic difference in size, it may be missing information. Always create a backup copy before replacing.

There's no guarantee that copying this file from another machine will restore all counters. If possible, compare the file to backups of the machine to see if the file size has reduced at some point in time. The PerfLib V2 implementation directly supports collecting data from V2 providers.

It does not support collecting data from V1 providers. V1 providers are implemented as a provider DLL that is loaded into the consumer process. The provider DLL is responsible for collecting performance data as appropriate , e.

V2 providers are implemented as either a user-mode program often a Windows service or a kernel-mode driver.

Usually the performance data provider code is integrated directly into an existing component i. This support is often hard to use in terms of authentication controls the tools and APIs can only authenticate as the current user as well as in terms of system configuration the necessary endpoints and services are disabled by default.

In many cases, it is better to access the performance counters of remote systems via WMI rather than via the built-in remote access support.

Performance counters are often consumed by administrators to identify performance issues or abnormal behavior of systems, by developers to study resource usage of software components, and by individual users to understand how programs are behaving on their system.

Performance counter providers are usually implemented as kernel-mode drivers or user-mode services. For information about run-time requirements for a particular programming element, see the Requirements section of the reference page for that element.

Tip It might be helpful to relate performance counter terms to more familiar spreadsheet terms. Note For backwards-compatibility reasons, the "Process" counterset returns non-unique instance names based on the EXE filename. The performance counter libraries may become corrupted and need to be rebuilt. This behavior may occur if certain extensible counters corrupt the registry, or if Windows Management Instrumentation WMI -based programs modify the registry.

Ensure that the counters are not disabled in the registry. The counters may be disabled via registry settings. Please check the following registry locations to ensure that the counters have not been disabled. There may be registry keys for " DisablePerformanceCounters " in any of these locations. As per the following TechNet article, this value should be set to 0. If the value is anything other than 0 the counter may be disabled.

A value of 1 means the counter is disabled. A value of 2 means the bit counter is disabled. A value of 4 measn the bit counter is disabled.
